A control apparatus includes: a rotor temperature estimation unit estimating a temperature of a rotor based on stator temperature information from a first temperature sensor for identifying a temperature of a stator, refrigerant temperature information from a second temperature sensor for identifying a temperature of refrigerant used to cool an electric motor, and rotation speed information about the rotor from a resolver for identifying a rotation speed of the rotor; and an electric motor control unit controlling at least one of an output characteristic and a drive condition of the electric motor based on the temperature of the rotor estimated by the rotor temperature estimation unit.

Control apparatus for electric motor and vehicle

A rotor for a rotary electric machine, the rotor including: a rotor core; a rotor shaft having a tubular shape, passing through a radially inner side of the rotor core to be coupled to the rotor core, and extending along an axial direction; an oil supply path that supplies oil to the rotor shaft, a portion to be lubricated that is disposed on a first axial side with respect to the rotor core, wherein one side in the axial direction is defined as the first axial side and another side in the axial direction is defined as a second axial side; and a lubrication oil path through which oil is supplied to the portion to be lubricated.
